This is really simple example code to get you some basic
functionality with the MonsterMoto Shield. The MonsterMote uses
two VNH2SP30 high-current full-bridge motor drivers.

Use the motorGo(uint8_t motor, uint8_t direct, uint8_t pwm)
function to get motors going in either CW, CCW, BRAKEVCC, or
BRAKEGND. Use motorOff(int motor) to turn a specific motor off.

The motor variable in each function should be either a 0 or a 1.
pwm in the motorGo function should be a value between 0 and 255.
